Weather - Get Weather Along Route

  • Reference
Service:
Maps
API Version:
1.1

Use to get a locationally precise, up-to-the-minute forecast that includes weather hazard assessments and notifications along a route.

The Get Weather Along Route API is an HTTP GET request that returns hyper local (one kilometer or less), up-to-the-minute weather nowcasts, weather hazard assessments, and notifications along a route described as a sequence of waypoints. This includes a list of weather hazards affecting the waypoint or route, and the aggregated hazard index for each waypoint might be used to paint each portion of a route according to how safe it is for the driver. When submitting the waypoints, it is recommended to stay within, or close to, the distance that can be traveled within 120-mins or shortly after. Data is updated every five minutes.

The service supplements Azure Maps Route Service that allows you to first request a route between an origin and a destination and use that as an input for Weather Along Route endpoint.

In addition, the service supports scenarios to generate weather notifications for waypoints that experience an increase in intensity of a weather hazard. For example, if the vehicle is expected to begin experiencing heavy rain as it reaches a waypoint, a weather notification for heavy rain will be generated for that waypoint allowing the end product to display a heavy rain notification before the driver reaches that waypoint. The trigger for when to display the notification for a waypoint could be based, for example, on a geofence, or selectable distance to the waypoint.

The API covers all regions of the planet except latitudes above Greenland and Antarctica.

URI Parameters

Name In Required Type Description
format
 path True

JsonFormat

Desired format of the response. Only json format is supported.
api-version
 query True

string

Version number of Azure Maps API.
query
 query True

string

Coordinates through which the route is calculated, separated by colon (:) and entered in chronological order. A minimum of two waypoints is required. A single API call may contain up to 60 waypoints. A waypoint indicates location, ETA, and optional heading: latitude,longitude,ETA,heading, where

  • Latitude - Latitude coordinate in decimal degrees.
  • Longitude - Longitude coordinate in decimal degrees.
  • ETA (estimated time of arrival) - The number of minutes from the present time that it will take for the vehicle to reach the waypoint. Allowed range is from 0.0 to 120.0 minutes.
  • Heading - An optional value indicating the vehicle heading as it passes the waypoint. Expressed in clockwise degrees relative to true north. This is issued to calculate sun glare as a driving hazard. Allowed range is from 0.0 to 360.0 degrees. If not provided, a heading will automatically be derived based on the position of neighboring waypoints.

It is recommended to stay within, or close to, the distance that can be traveled within 120-mins or shortly after. This way a more accurate assessment can be provided for the trip and prevent isolated events not being captured between waypoints. Information can and should be updated along the route (especially for trips greater than 2 hours) to continuously pull new waypoints moving forward, but also to ensure that forecast information for content such as precipitation type and intensity is accurate as storms develop and dissipate over time.
language
 query

string

Language in which search results should be returned. Should be one of supported IETF language tags, case insensitive. When data in specified language is not available for a specific field, default language is used.

Please refer to Supported Languages for details.

Request Header

Name Required Type Description
x-ms-client-id

string

Specifies which account is intended for usage in conjunction with the Microsoft Entra ID security model. It represents a unique ID for the Azure Maps account and can be retrieved from the Azure Maps management plane Account API. To use Microsoft Entra ID security in Azure Maps see the following articles for guidance.

Security

AADToken

These are the Microsoft Entra OAuth 2.0 Flows. When paired with Azure role-based access control it can be used to control access to Azure Maps REST APIs. Azure role-based access controls are used to designate access to one or more Azure Maps resource account or sub-resources. Any user, group, or service principal can be granted access via a built-in role or a custom role composed of one or more permissions to Azure Maps REST APIs.

To implement scenarios, we recommend viewing authentication concepts. In summary, this security definition provides a solution for modeling application(s) via objects capable of access control on specific APIs and scopes.

Notes

  • This security definition requires the use of the x-ms-client-id header to indicate which Azure Maps resource the application is requesting access to. This can be acquired from the Maps management API.

The Authorization URL is specific to the Azure public cloud instance. Sovereign clouds have unique Authorization URLs and Microsoft Entra ID configurations. * The Azure role-based access control is configured from the Azure management plane via Azure portal, PowerShell, CLI, Azure SDKs, or REST APIs. * Usage of the Azure Maps Web SDK allows for configuration based setup of an application for multiple use cases.

Type: oauth2
Flow: implicit
Authorization URL: https://login.microsoftonline.com/common/oauth2/authorize

Scopes

Name Description
https://atlas.microsoft.com/.default https://atlas.microsoft.com/.default

subscription-key

This is a shared key that is provisioned when you Create an Azure Maps account in the Azure portal or using PowerShell, CLI, Azure SDKs, or REST API.

With this key, any application can access all REST API. In other words, this key can be used as a master key in the account that they are issued in.

For publicly exposed applications, our recommendation is to use the confidential client applications approach to access Azure Maps REST APIs so your key can be securely stored.

Type: apiKey
In: query

SAS Token

This is a shared access signature token is created from the List SAS operation on the Azure Maps resource through the Azure management plane via Azure portal, PowerShell, CLI, Azure SDKs, or REST APIs.

With this token, any application is authorized to access with Azure role-based access controls and fine-grain control to the expiration, rate, and region(s) of use for the particular token. In other words, the SAS Token can be used to allow applications to control access in a more secured way than the shared key.

For publicly exposed applications, our recommendation is to configure a specific list of allowed origins on the Map account resource to limit rendering abuse and regularly renew the SAS Token.
